When Carey's sister, Amy, heard the news, she said: "That's impossible. She works, she holds a job. She wouldn't be in D.C. She was just in Connecticut two days ago, I spoke to her.. . . I don't know what's happening."

Sara Vega, a former classmate of Carey's, called her a really "sweet and nurturing person." Another former classmate said she was always professional and focused on improving her life.

Carey was shot and killed after running into a barrier and hitting a Secret Service officer at the White House. Police pursued her car to Capitol Hill, where the chase ended.

She had her 1-year-old daughter in the car with her during the pursuit.
